G AG E SPECIFICATION forming part of Letters Patent No. 559,450, dated May 5, 1896. Application filed January 13, 1896. Serial No. 575,311. (No model.)

To au whom, t may concern.-

le it known that we, ANDREW JOHNSON IIASKELL and JOSEPH BENTON I-IAsKELL, citizens of the United States, residing at Vaterford, in the county of Oxford and State of Maine, have invented certain new and useful Improvements in Gages, of which the following is a description,reference being had to the accompanying drawings, and the letters of reference marked thereon.

Our invention relates to improvements in gages, and more particularly to gages of the kind used in connection with power-driven saws,whether circular, bent, or reciprocating.

Many uses of our invention will occur to those skilled in the art, and we therefore do not attempt to'enumerate them all.

As indicated in the drawings, the invention is illustrated in connection with the table of a circular saw, and the invention is embodied in .an apparatus for adj Listing the usual sawtable gage to a number of dii-ferent positions with relation to the saw, so that the gage may be set to eut successive pieces of the same or of differing widths by the predetermined operation of our adjustable stops.

In the accompanying drawings, Figure l is a plan view of part of a saw-table embodying our invention in duplex form. Fig. la is a detail made as a projection from Fig. l, showing some. of the parts of said igure in elevation, partly in section. Fig. 2 is an elevation of the device where a single set of stops only are employed. Fig. 3 is a detail on the line 3 3 of Fig. 2. Fig. et is a plan view showing a slightly-modified form of the gage-stops. Fig. 5 is alsoa plan view showing the gagestops arranged on the disk instead of projecting radially from the cylinder.

As indicated in the drawings, A is the sawtable; B, the saw; C, the gage, whichis to be moved toward or away from the saw and in a line parallel therewith to determine the width or thickness of the piece to be cut off by the saw. j

Our invention relates particularly to the means for adjusting the gage C, which comprise a series of adjustable pins which are to be set to project the desired distance for the successive cuts, after which means connected with the gage O are placed successively against the pins to determine the successive positions oi'l the gage with respect to the saw.

D E F G represent four pins,which, as seen in Fig. l, are secured at their rear ends in a stationary head H, which is best secured to a tubular shank nwhich is carried in trunnions I. The stops D E F G are arranged in the are of a circle and two similar sets are provided.

.O O2 are rods secured to the gage and extending across the table A, so that their opposite ends enter and are guided in the tubular Shanks h. Guides CZ are mounted upon trunnions e,l and through these pass the rods C C2 to give greater steadiness to the gage C under the vibration of the saw. Adjustingblocks J are rotatably secured upon the rods O O2, and said blocks are each provided with a projecting lug j, which lugs, when the blocks J are turned, are adapted to engage and to abut against the stops D E F G as they are moved into the path of each pair thereof. Levers K are connected with each one of the blocks J and are pivoted upon extensions A of the table A. By means oi these levers K and suitable connections the rods C C2 and the gage C are moved toward or away from the saw B. Suitable connections for the levers K may comprise connecting-rods 7.; 7a, which are brought together at their ends nearest the saw and pivotally connected with the lower end of a lever a, which is pivoted in an opening a/ in the saw-table A. This lever may be carried up straight, as indicated in Fig. l, or may be provided with an additional operating-handle arranged in a horizontal plane similar to the lever M in Figs. 4 and 5. The blocks J J are connected by rod j', to which is attached a handle y2, by which the blocks J are turned upon the rods C C2, so as to bring the lugs jy' in line with either'pair of the stops D E F G, and when said lugs are against the stops the gage will be at the proper distance from the saw, thereby determining the width of the work to be cut. `By suitable connection to rods 7s, attached to the lower ends of the levers K, the gage, with-its rods O G2 and parts connected thereto, may be moved toward and away from the saw from a single point.

IOO

As seen in Fig. 4, a shorter gage O is shown, said gage being provided With a stem L. Stops D4 E4 F4 G4 are arranged horizontally, projecting radially from the periphery of a cylinder Z, rotatably mounted upon the table A. A hand-lever M may be secured at one end to the table A and pivotally connected to the stem L for conveniently moving the gage back and forth. The stops on the cylinder Z are so arranged that any one of them may engage and form an abutment for the stem L, so that by rotating the cylinder Z any one of the stops carried thereby may be placed in the path of the stem L and the position of the gage determined thereby. As seen in Fig. 5, the stem L of the gage O is arranged to move in a guideway N, and in this instance the stops D5 E5 F5 G5 are adj ustably secured in a disk O, which is secured upon a shaft O, Which is suitably journaled parallel with the table A and with the guideways N. With this construction the adjustment is slight, the gage O being set by the abutment of a projection Z' upon the stem L' thereof against the desired one of the stops, a hand-lever M, similar to that already described, being employed to move the gage and its stem.

As indicated in Figs. 2 and 3, stoppins D E F G are arranged in the stationary head H, having tubular stern 7L. The rod C', passing through guide d, is connected to and actuates the gage O. A rotatable block J, provided with lugj, is secured to the stem O', and said block is provided With a handle J', by which it is rotated to bring the lug opposite to the desired one of the stops. The gage may be moved back and forth by means of the handle J attached to the block J, Which is r0- tatably secured to the rod C', but We may in addition thereto provide the gage With a handle P, for more conveniently moving' it, if desired.

Various minor modifications may be made in this our invention by persons skilled in the art to which it relates, in View of the foregoing description of its nature and purpose, Without departing therefrom.

Having described our invention, what We claim isl. The combination With an adjustable gage, of a support for holding said gage, a series of adjustable stops of different lengths, a part connected With the gage-support adapted to engage one or other of the stops, and a rotary device for bringing the gage-support and stops into engagement, as desired.

2. The combination With a saw and its table, of an adjustable gage for directing the Work of the saw, a support or supports extending from the gage, a series of adjustable stops of different lengths and a rotatable projection secured to the gagesupport and provided With a suitable handle for operating the same, and adapted to engage one or other of the adjustable stops to determine the position of the gage.

3. The combination With a savvv and its table, of an adjustable gage for directing the Work of the saw, supports extending from the gage, a series of adjustable stops of differentlengths, rotatable projections, as blocks J, secured to the supports of the gage, levers K, connecting-rods extending therefrom, and a pivoted operating-lever connected pivotally with the connecting-rods, whereby the gage and the rotating projections are moved toward and away from the stops as desired.

In testimony whereof We hereto aflix our signatures in presence of tWo Witnesses.
